Abstract

A portable ultrasonic diagnostic device, according to the present invention, comprises: a transducer for generating an ultrasonic pulse from an applied electrical pulse, irradiating the ultrasonic pulse to a subject to be diagnosed, and receiving an echo signal; and a main circuit unit for generating an electrical pulse which is to be applied to the transducer, generating scanline data from the echo signal, and transmitting to a portable terminal the scanline data or frame data which comprises a predetermined number of scanline data items, wherein the main circuit unit transmits the scanline data or the frame data, during the time other than the time in which the echo signal is received, and generates the electrical pulse during the time other than the time in which the scanline data or the frame data is transmitted.

1 . A portable ultrasonic diagnostic device comprising:
 a transducer which generates and emits an ultrasonic pulse from an applied electrical signal toward an object to be inspected and receives an echo signal therefrom; and   a main circuit portion which generates an electrical pulse to be applied to the transducer, generates scan line data from the echo signal, and transmits the scan line data or frame data including a certain number of scan line data to a portable terminal,   wherein the main circuit portion transmits the scan line data or the frame data during a time except a reception time of the echo signal and generates the electrical pulse during a time except a transmission time of the scan line data or the frame data.   
     
     
         2 . The portable ultrasonic diagnostic device of  claim 1 , wherein the main circuit portion transmits the scan line data when the reception time of the echo signal is completed, and generates an electrical pulse for a next scan line when the scan line data is completely transmitted. 
     
     
         3 . The portable ultrasonic diagnostic device of  claim 2 , wherein the main circuit portion comprises:
 a pulse generator which generates the electrical pulse;   a beam former which generates the scan line data by beam-forming the echo signal; and   a processor which transmits the scan line data,   wherein the processor transmits the scan line data when the reception time of the echo signal is completed, and   wherein the pulse generator generates the electrical pulse for the next scan line when the scan line data is completely transmitted.   
     
     
         4 . The portable ultrasonic diagnostic device of  claim 3 , wherein the main circuit portion further comprises a buffer which stores the scan line data, and
 wherein the processor transmits the scan line data stored in the buffer when the reception time of the echo signal is completed.   
     
     
         5 . The portable ultrasonic diagnostic device of  claim 2 , wherein the reception time of the echo signal is determined according to a set diagnosis depth of the portable ultrasonic diagnostic device. 
     
     
         6 . The portable ultrasonic diagnostic device of  claim 1 , wherein the main circuit portion transmits the frame data when a reception time of an echo signal for a last scan line, which forms a frame, is completed, and generates an electrical pulse for a first scan line of a next frame when the frame data is completely transmitted. 
     
     
         7 . The portable ultrasonic diagnostic device of  claim 6 , wherein the main circuit portion comprises:
 a pulse generator which generates the electrical pulse;   a beam former which generates the scan line data by beam-forming the echo signal;   a buffer which stores the generated scan line data; and   a processor which transmits frame data including a certain number of the scan line data stored in the buffer,   wherein the processor transmits the frame data when the reception time of the echo signal for the last scan line is completed, and   wherein the pulse generator generates the electrical pulse for the first scan line of the next frame when the frame data is completely transmitted.   
     
     
         8 . The portable ultrasonic diagnostic device of  claim 7 , wherein the reception time of the echo signal is determined according to a set diagnosis depth of the portable ultrasonic diagnostic device. 
     
     
         9 . A method of operating a portable ultrasonic diagnostic device, comprising:
 emitting an ultrasonic pulse toward an object to be inspected and receiving an echo signal therefrom;   generating scan line data from the echo signal when a reception time of the echo signal is completed, and transmitting the scan line data to a portable terminal; and   emitting an ultrasonic pulse for a next scan line when the scan line data is completely transmitted.   
     
     
         10 . A method of operating a portable ultrasonic diagnostic device, comprising: (a) emitting an ultrasonic pulse toward an object to be inspected and receiving an echo signal; (b) generating scan line data from the echo signal when a reception time of the echo signal is completed;
 generating frame data including a certain number of scan line data by repeatedly performing operation (a) and operation (b); transmitting the generated frame data; and   emitting an ultrasonic pulse for a first scan line of a next frame when the frame data is completely transmitted.
